Our invention relates to a method of form ing manifolding copies which shall be perforated as well as imprinted with acolored impression so as'to be entirely safeagainst sub uent alterations, the impression on the original and all manifold copies being of a type similar to impressions made by check protective printing muse at the'present.

There are several types of structures whereby writing can be done in characters which are perforated, the chief one being by means of type faces formed ofpin points which netrate the paper, said oints being covere with ink or other suita ,le medium which will leave a color around the peripheries of the holes. Devices have also been constructed which operate after'the fashion of apdentists tool on a flexible shaft, which have a rapidly reciprocating point which will penetrate paper .and leave a perforated impression. .Our invention isalso applicable for use with such devices.

We have illustrated our invention as applied to an Elliot Fisher manifolding typewriter machine, but it will be understood that this is for purposes of convenience.

We accomplish our ob ect 1n manifolding.

with perforated impressions in that manner to be hereinafter more specifically pointed out and claimed.-

Figure 5 is a detail, partly in sectioln'showing a printin' character of which the type face .isforme of pins for perforating manifolding forms. v

Referring briefly to the drawings we show a t writer 1 mounted to move to and fro an forward and back on a frame 2. A storage roll for manifold paper webs, such as printed forms, is shown-at 3, which pap r detail showing the type abutrange long. shift the cloth with the printing mechanismfii V v plugs of felt 7a on their to s, which revent the pins from being blunte if more t an one type bar is operated at once. Thetypewriter is equipped with-a bifurcated plate 8 at the printing point, having an orifice between the arms thereof, which plateis mounted as desired upon the typewriter, and is spaced slightly from the paper. The type faces on the type arm of the typewriter are so arinto the space between the armsof the plate 8, with t e type-bodies coming up against the plate arms as a stop.

y In Figure 4 the ribbon 9 is illustrative of the usual ribbon of the Elliot Fisher t pewriter. There are tough ribbons made w 1ch will stand the penetration of pin-type faces toa considerable extent without tearing or breakin We have not shown the ribbon guide 0 the machine will lie under the plate 8 where it isbent down toward theplaten of' the machine.

The webs of pa r 3a, where they pass along the platen neath the typewriting machine, will be interleaved'with bands of printing cloth. formed of like material to the tough printing ribbonslast above referred to. The strips of cloth lOa'may be wound an rollers as indicated at,=10 and" 11", and thus can be renewed from time to time as're uired: The cloth will be as wide astle port1onof the-paper, which is exposedfor-purposesgof being impressed with desired characters,a-:.

Otherwiseit would be necessary to which would be impractical-- 3 i In following our method-of printing, pin t pe faces are brought down overt e-asthe machine, so that th'eTpins penetrate through the printing ribbon, theseveral forms, and

that the pin itype faces come down semb ed printedforms on theplaten'of"the,*-* 169 with ordina the printing cloth between the several forms.

It is not practical to use printin cloth. t faces, althoug this would be conslde le of a saving in trouble of handling carbon paper and renewing the same. The reason for this is that the cloth with the paper between it-makes a soft body, which acts like a pillow to the type, and thus prevents any blow such as is required to make a proper impression, and roduces a blurred impression which is hardly l ible. With the perforating pins as the type aces, however, the ins will netrate, or at least deform, each ayer of t e pile of paper and cloth, and forms an excellent impression which it is not ractical to alter. The pins re ily penetrate the cloth an receive the ink from the cloth in such a way 'written or am.

Having t us descri d our invention, what we claim as new and desire to secure by Letters Patent, is

1. A process for forming impressions in manifolding, which consists in passing'a perints 12 surrounded by inked walls or paper for renewing the same, and forming A impressions on the paper while stationary on the platen, by passing into the paper and cloth a pin or pins arranged as characters, at

various points, for the purpose described.

6. A recess for forming impressions'in manifol ing, which consists in arranging a .set of paper'forms with printing cloth transversely interleaved therewith, and passing a pin or pins through the assembled layers.

7. A process for forming impressions in manifolding, which consists in arranging a set of paper forms with printing cloth transversely interleaved therewith, and of a width equal substantially to the length of the portion of the printed form to be filled in, and

passing a fpm or pins throu ii the assembled ayers to orm the desired c aracters in each of the" set of forms.
